B4C powder MF: B4C

B4C powder CAS No: 12069-32-8

B4C powder EINECS No: 235-111-5

B4C powder Appearance: Grey black powder

B4C powder particle size: Can customized according to requirements.

Boron Carbide Properties:
The formula of Boron Carbide is B4C. Boron carbide crystals are hexagonal. Boron carburide density reaches 2.52g/cm3. Boron carbide has a melting point of 2450

Boron carburide hardness (B4C): Mohs hardness is 9.3; its microhardness range is between 55006700kg/mm2. It is only second to the hardest material cubic boron-nitride and diamond.

Boron carbide possesses low density, high strength and high temperature stability, as well as good chemical stability. Boron carbide is used widely in ceramic reinforcing phases, wear-resistant material, and lightweight armor.

ceramic boron carbide has a lower cost and is more easily manufactured than diamond or cubic boron. It is also used more often because it is cheaper. It can be used to replace diamonds, which are expensive, in certain places.

B4C powder is high-purity, has small particle sizes, and high surface specific area. B4C, on the other hand, is synthetic, ultra-rigid material, with a hardness of 9.46. It also has microhardnesses between 56-6200 Kg/mm2, a proportion of 252g/cm3, a melting temperature at 2,250° Celsius.
Chemical properties: resistant to strong acids, alkalis, and high and low temperature. It can also absorb neutrons and emit gamma-rays, which are harmful to human health.

Boron carbide is a very stable substance in acidic solutions. It is also stable in alkali or concentrated acidic aqueous solution. Boron carbide remains stable in an atmosphere below 800degC. The boron oxidation product is lost to the gas phase and leads to its instabilities and oxidation into carbon dioxide and Boron trioxide.

How does Boron Carbide B4C Boride Powder get produced?
Boron Carbide (B4C) Boride Powder is created by reducing carbon with boron at high temperature in an electric furnace. The powdered black is solidified after it has been ground at temperatures above 2,000degC. Its melting temperature is about 2,350degC.

Boron Carbide B4C Powder Uses:

Fine and Advanced Abrasive Materials
It is used in grinding processes for hard materials such a gems or ceramics. Also, it can be used to drill and polish bearings.
Industrial ceramics
The following products are made from boron-carbide powder as a novel material: sandblasting nodes, seal rings, nozzles bearings plungers for mud pumps pestles rocket launchers ceramic coatings warships helicopters etc. It is widely used as a sandblasting machine, in electronics, information, aviation, automobile, and other industries.
Materials for shielding and controlling the nuclear industry
The Boron Carbide material has an excellent neutron resistance and absorption as well as a large thermal neutron section. It is widely recognized internationally and used for shielding materials and nuclear reactor control.
Bulletproof armor
Its high strength and low specific gravity make it ideal for the manufacture of lightweight bulletproof armour, which is used to protect aircrafts, vehicles, ships, and even human bodies.
Increase life expectancy of mechanical components
Mix boron-carbide powder with metals to create metal-based powder. After a special treatment, original mechanical components are more resistant to corrosion and wear.
Special absorber provides energy
The solid fuel rocket uses boron carbide (also known as black gold) as an energy source.
Chemical additives
Because of its high chemical potential and stable chemical properties, it is used widely in the production other boron containing materials such as zirconium and titanium borides.
Advanced refractories
It is widely used to make steel stoves, kiln furniture, and other refractory products.

Storage condition of Boron Carbide powder B4C:
B4C Powder dispersion and use effects will be affected by damp reunion. Therefore, the B4C Powder should be packed in vacuum and kept in a dry and cool room. The boron carbide powder should not be exposed to stress.

Shipping & Packing of Boron Carbide (B4C) powder:
